Practical work is essential for science education. But health measures compromise their traditional organization. Here are some game-changing solutions.
Most people never have the chance to see how animals live in laboratories.
Since 2012, more than 120 of Britain’s universities, research institutions and pharmaceutical companies have signed a public pledge committing them to greater openness in their animal research programs.
The study looked at helping redheads to tan and protect them from the sun. But the redheads were mice, not humans.
A US study into whether a new drug can give us a tan without going into the sun generated headlines around the world. Here’s what the study really says.
